Replai

Replai is an AI-native platform designed to help banks, insurers, reinsurers, and enterprise fintechs understand, maintain, and modernize mission-critical legacy systems. Its Agentic AI platform reads legacy codebases—including COBOL, Oracle Forms, PL/I, PowerBuilder, Delphi, Natural, IBM RPG, and others—and builds a structured semantic knowledge layer that maps business rules, workflows, and component dependencies. Replai enables natural-language querying of legacy code, dependency graph visualization, regulatory compliance and audit trail reconstruction, metadata recovery, risk and impact analysis, and AI-assisted modernization including code migration (e.g., Oracle Forms to Oracle APEX). The company also operates a partner program for system integrators seeking to deliver legacy modernization engagements with higher margins and faster timelines. Replai reports having analyzed over 2 billion lines of code across 100+ modernization projects.
